Iraq's parliamentary speaker has summoned lawmakers to a special meeting of the National Assembly on Monday, the deadline for completing a draft constitution.

Sunni, Shi'ite and Kurdish negotiators are racing to finish the draft, though officials say no final agreement has been reached yet.

Reuters news agency quotes members of the constitution drafting committee as saying lawmakers will get their first opportunity to review a text of the new charter at Monday's special assembly session.

Meanwhile, there are reports that a director of the Iraq Central Bank has been kidnapped in Baghdad.

Separately, U.S. officials say five American soldiers have been killed by roadside-bomb explosions since late Friday in Baghdad, Tuz, and at Rutbah, in far western Iraq.
